Hepatology is a rapidly evolving medical field and will continue to be very exciting over the next few decades. The situation in viral hepatitis is similar to the HIV field 10-15 years ago when it started to become better understood and treatable. Today,
hepatitis B viral replication can be suppressed by potent antiviral drugs but there are risks for the emergence of resistance. Strategies to enhance the eradication rates of
HBV infection still need to be developed. On the other hand, hepatitis C virus infection can be eradicated by treatment with pegylated interferon plus ribavirin. However, particularly in those infected by HCV genotype 1 the sustained virologic esponse rates are still suboptimal. Many new antiviral drugs, especially protease and polymerase inhibitors, are currently in preclinical and clinical development, and the first data from larger clinical trials provide some optimism that the cure rates for patients with chronic hepatitis C will be enhanced with these new agents. In other areas of hepatology, e.g., for hereditary and metabol ic liver diseases, our knowledge is rapidly increasing and new therapeutic options are on the horizon. |
